Built my current PC in 2011, and it's time for an upgrade. I have no idea what is good/recommended anymore, help?

It's time for an upgrade, my machine is lagging just doing autocad and it's going to cause me to break my mouse in anger. I've been out of the loop for so long I have no idea what people are recommending anymore. For a while, people were recommending AMD over Intel, is that still a thing? Basically, I have between $2,000 and $3,000 to spend on a new machine, not including the video card, but I'll need everything else. Proc, Mobo, Ram, Power supply, Case, and 1 new SSD (I'll re-use my existing SSD's as well along with my 3070 for now).

The machine is going to be used for both gaming and Autocad. Any help is appreciated. Thanks!
